Application flied september 23,1905. serial No. 279,805.

To all. whom/t may concern: Be it known that I, OswALD S. PULLIAM, a

citizenof the United States, residing at Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Metallic Railway-Ties, of which the following is specification.

'The object of my inventionis to provide a vnew andy improved metallic railway-tie; and

to this end the present invention consists of a metallic railway-tie, in the construction and-in the combination of parts all as hereinafter described and claimed.

In the accompanying drawings,1 which illustrate applications of my invention, Figure 1 is a perspe'ctiveview of several ties constructed in accordance with my invention applied,to two rails ;"Fig. 2, a broken View of a modified'form of tie in side elevation; Fig. 3, a view similar to Fig. 2, showing a different arrangement of slots in the web; and Fig. "4, aA detail vertical sectional view.

Referringl to the drawings, A and B represent two railsv of the usual form.

' My invention comprises a beam having a top member' 1 ab'ottom, vmember 2, and a vertical web 3.,'and, as illustrated and as preferredthe tie is constructed of a rolled or cast structural beam in the form of an I- beam. In the forms of ties shownu by the ldrawings Iemploy two sets of engaging lugs of securin the rails yto the tics.

4, whichare adapted to be bent over to en-y gage the rail-bases.l These lugs, as shown,

are. formed integral with the top member 1; but I-donotdesire to be limited to this mode 'The vertical web 3 is formed at each end in the form -offFig 1 with a slot 6 and 'in the 45..

lform of Fig. 2 with a plurality of similar, slots. These slots extend inwardlyfrom tlie 'ends of the tie for a sufficient distance to give the re# quiredr amount of spring to the ties as the load isA passing-over.

1. A metallic railway-tie comprising a cast structural beam having a vertical web and top and bottom members, and means for giv- Formed in# ing elasticity to the tie comprising a slot formed in the web, substantially as set forth.

2. A metallic railway tie vcomprising a beam having a vertical web and means for giving elasticity to the tie 'comprising top and bottom members, and a horizontaliydisposedslot formed in the web, substantially as set forth.

A metallicl railwaytie comprisingy a rolled structural beam having a vertical web and top and bottom members, and means for giving elasticity to the tie comprising a slot formed .in the web at each end of the beam, substantially as set forth..

4. A metallic railway-tie comprising a beam having a vertical web and top and bottom members, and means for giving elasticity to the tie comprising a plurality of slots formed in the web, substantially as set forth.

5. A metallic railway-tie comprising a rolled structural I-beam having means for giving elasticity to the tie comprising a hori zontally-disposed slot formed .in the web thereof, substantially as set forth.

6. A metallic railway-tie comprising a rolled structural I-beam having means for giving elasticity to the tie comprising a horizontally-disposed slot formed in the web at each 4end ofthe beam, substantially as` setl forth.

' 7. A metallic railway-tie comprising a rolled structural I-beam having means for giving elasticity to the tie comprising a plurality of horizontallydisposed slots formed in the web of the beam, substantially as set forth. j

8. A metallic railway-tie comprising a beam having a vertical web and top and bottom members, means for giving elasticity to the tie comprising)horizontally-disposed slots formed in the web, and outwardly-extending projections formed integral with the web,

substantially as set forth.

9. A metallic railwaytie comprising a beam having a vertical web and top and bottom members, engaging lugs formed intefrral with the top member, means for giving elasticity to the tie comprising horizontally-disposed slots formed in the web, and. outwardly-extending projections formed integral with the web, substantially as setl forth.'l

l0. A metallic railway-tie 'comprising an I-beam having horizontally-disposed slots lOO IOC

formed in its web for giving elasticity to kthe l tie, engaging lugs formed integral With its top member, and outwardly-extending projections formed integral With the web, substan- I tially as set forth.

11. A metallic railway-tie comprising en -beam having a horizontally-disposed slot formed in its Web at each end of the beam for giving elasticity to the tie, engaging .lugs

outwardly-extending projections formed 1nte ral with the Web, substantially'as set forth.

n testimony whereof I affix my signature in presence of two subscribing Witnesses.
